PATENT QFFICEO OF GRINNELL, IOWA, ASSIGNOR TO OF DALLAS, TEXAS, A

COFFEE-URN.

Application filed February 16, 1905. Serial No. 245,9 t7.

To (all whom it may concern.-

Be it known that I, OULLEN ANnRnwRoB- ERTSON, a citizen of the UnitedStates, residing at Grinnell, in the county of Poweshiek and State ofIowa, have invented certain new and useful Improvements in Coffee-Urns;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in coffee pots or urns; and itconsists in certain novel features of construction, combination, andarrangement of parts hereinafter described and claimed.

The object of my invention is to improve and simplify the constructionand operation of devices of this character, and thereby render the samemore convenient and eflicient in use and less expensive to manufacture.

The above and other objects, which will appear as the nature of myinvention is betterunderstood, are accomplished by the constructionillustrated in the accompanying drawings, in which Figure 1 is a sideelevation of the coffeeurn constructed in accordance with my invention.Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectionalView, and Fig. 4 is a side elevation of the strainer-supporting frameremoved from the urn.

Referring to the drawings by numeral, 1 denotes my improved coffee potor urn, and 2 denotes a base or stand upon which the same is supported.This stand is provided for the purpose of protecting the table or thelike upon which the device is placed, and it consists of a base-plate 3,having at one end araised circular portion 4 to support the bottom ofthe coffee-pot and at its opposite end a circular band or ring 5,adapted to receive a cup or other receptacle into which coffee from theurn 1 is to be poured. The portion 4: of the stand has its top and sidesformed with openings 6, which permit of a free circulation of airthrough the same to prevent the stand from becoming as hot as thecoffeeurn. Said portion t is also formed at its top and having its spoutwith an annular flange 7 which is adapted to prevent the cofl'ee-urnfrom slipping off of the same.

The coffee-urn 1, as shown, consists of a cylindrical body portion 8,having an open top and an outwardly flared or enlarged lower end 9, itsbottom 10 having its seam or connection 11 with the lower end of thecylindrical body8 above the plane of said bottom, so as to prevent thedanger of the solder in said seam becoming melted by the flames or heatof the fire over which the coffee in the urn is made. The lower end 9 ofthe coffeeurn is flared or enlarged, so as to render the same lessliable to be overturned and to increase the heating-surface which is incontact with the stove when coffee is being made in the urn. Somedistance above the enlarged end 9 of the body 8 is ahorizontally-disposed V-shaped outlet conductor or pipe 12, which has atits inner end a fine screen or strainer 13 and at its outer end adischarge-faucet 14:. The latter is of well-known form, having a turningplug-valve operated by a handle 15 16 so disposed that when thecoffee-urn is placed upon the portion 4 of the stand 2 the coffeedischarged from said spout will fall into a cup and saucer placed uponthe supporting-ring 5. In order to facilitate the discharge of thecoffee from the urn, I provide an air-vent tube 17 which has its lowerend projecting from and in communication with the interior of theoutlet-pipe 12 and its upper end extending inwardly at right angles, asshown at 18, and openinginto the upper portion of the body 8 at asuitable point below the cover 19 upon the latter. The upper portion ofthe tube 17 is formed with an opening 20, which permits air to enter thecoffee-pot for the purpose explained Upon the rear portion of the body 8is provided a handle 21, which preferably consists of two pieces ofheavy wire coiled intermediate their ends, as shown at 22, to form ahand-grip and having their ends bent outwardly, as shown at 23, andsoldered upon the outside of the body 8. The ends of these wires at theupper and lower ends of the hand-grip are bent in opposite directions,sothat thelatter will be prevented from turning or twisting. The cover 19of the body 8 of the coffee-urn is removably held upon the same by abroad flange 24, which engages the interior of the upper end of the body8, so as to form a fluid-tight closure. Said cover has a flared portion25, which permits it to be readily applied to or removed from the body8, and for this purpose a handle 26 is also provided upon the center ofthe top plate 27 of said cover. Said handle 26, as shown, consists of asingle piece of heavy wire coiled, as shown at 28, and having its ends29 projecting through the plate 27 and bent at right angles, so as topermit them to be readily soldered, as shown at 29.

Within the body 8 is a strainer 30, which may be raised and loweredtherein. The latter consists of a strainer fabric 31, a supporting orholding frame 32 therefor, and an operating handle or device 33. Theframe 32 comprises a tapered ring or circular band 34, which is ofslightly less diameter than the interior diameter of the body 8 andwhich has an inwardly-projecting annular flange 35, to which the handleor operating device 33 is secured. The latter is in the form of a longbail, which is slidably mounted in the cover 19 and which, as shown, isformed of a single piece of heavy wire coiled upon itself,as shown at33, to form a hand-grip, and having its legs 38 projecting through andsliding in openings 39, formed in the top plate 27 of said cover.Suitable stops 40 are provided upon the legs 38to limit the downwardmovement of the strainer in the body 8. The strainer fabric, which maybe of any desired form, is adapted to cover the bottom and sides of theframe 32 and engage the inner face of the body 8, so as to cause thestrainer to fit snugly therein.

When it is desired to make coffee in the urn, the cover and strainer areremoved and the ground coffee and boiling water are then placed in thebody 8. The cover is then placed upon the top of the latter and thestrainer 30 is elevated or drawn up into the upper portion of the bodyuntil the contents of the same has boiled about a minute. I then removethe urn from the stove or heater, so that its contents will not boil foracouple of minutes, and then move the strainer to the lower portion ofthe body, so that it will be disposed between the cofleegrounds upon thebottom 10 and the outletpipe 12, as shown in Fig. 3 of the drawings.When the parts are in this position, coffee will pass upwardly throughthe strainer fabric 31, and all grounds will be retained beneath thesame in the enlarged portion 9 of the body.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A coffee-pot comprising a cylindrical body having a flared or enlargedbottom, a coiled wire handle at one side of said body, an outlet-pipe atthe other side of said body, a strainer in said outlet-pipe, a faucet insaid outlet-pipe an air-vent tube between said outlet-pipe and the upperportion of said body and formed with an air-inlet opening, a removablecover upon said body, a strainer slidably mounted in said body, and anoperating-handle for said strainer projecting through said cover, saidstrainer being adapted to be raised and low ered between the bottom ofsaid container and said outlet-pipe, substantially as described and forthe purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
